+## Add secrets to a remote
+
+As above, you can pass a _{{secret_token}}_ to your remote doctype. In local, you can directly pass it as a request param in _io.cozy.doctypes/org.ecolyo.usage_.
+Otherwise, you will have to add it in the shell script _easy-cozy/db-init.sh_ on the server. You can add the following line to the file in order to add the secret in the database :
+
+```
+docker-compose exec db curl -X PUT -d "{\"_id\":\"org.ecolyo.dju\",\"token\":\"${API_DATAGRANDLYON_TOKEN}\"}" http://127.0.0.1:5984/secrets%2Fio-cozy-remote-secrets/org.ecolyo.dju
+```
+
+Make sure you have the right remote doctype name as \_id.
+
+Then, in the .env file, just add your token variable.
